concern:

lowering the shade and wherein the friction of the parts is reduced to a minimum and to provide a shade roller of simple construction and of cheap manufacture. v

The invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof in which- Figure 1 is a front elevational view of a shade roller'ernbodying the main features of my invention, the figure showing the shade in two parts for convenience of illustration;

Fig. 2 is a similar vlew, but illustrating the shade roller afiiXed between the inner facing strips of the window, Fig. 3 illustrating the metal bracket for so attaching to the inner facing strips.

Fig. 4 is a side elevatlonal view of the bracket supporting the operating end of the roller, and the lever for operating same.

Fig. 5 is an end view of the roller illustrating the ratchet wheel and showing the cord wound on the drum.

Fig. 6 is a detail sectional view of one end of the roller, illustrating the means of inserting the spindle carrying the drum and ratchet wheel, and

Fig. 7 is a side elevational view of the wheel broken away.

Referring more particularly to the drawings, 1 denotes the roller, 2 the shade and 3 the window frame to which is attached a bracket 4 with a bearing, not shown, for supporting one end of the roller pin or shaft, also not shown. A bracket 5 is provided at the opposite end of the roller wherein is supported the pin or shaft 6. This bracket 5 has a diagonally slotted opening 7 terminating in a I, PRIMUS W. SMITH,

bearing 9 in which is supported the pin or shaft 6. In Fig. 2 the shade and roller are shown suspended between the inner window facings and for that purpose there is provided the form of bracket illustrated in Fig. 3.

. The roller 1 has at each end the usual metallic cap 8 perforated to receive a spindle 10 formed integral with a drum 11. The

drum 11 has a transverse slot '12 into which one end of a flexible cord 13 is placed before inserting the spindle into the roller. By this means the cord is firmly secured to the drum 11. The spindle 10 is pointed at one end and the body may be either of square or oval formation to more firmly secure the spindle in the roller 1.

On the outer end of the drum 11 is secured a ratchet wheel 14:. This ratchet wheel has a collar 15 which abuts a circular projection 9 Fig. 4:, over the bearing 9, which projection together with the collar prevents the lever 16 and ratchet wheel 14 from frictional engagement. This lever 16 is pivoted to the bracket 5 at the point 17 and has a shank bent atright angles to form a lip in which is a circular eye 18 for receiving the cord. The opposite end of the lever 16 is relatively heavyin order that when released by the cord it will quickly fall between the teeth of the ratchet wheel 14:, and intermediate the ends of the lever is a pawl 19 to engage the teeth of the 'wheel. A slight pull downward on the cord 13 will disengage the pawl 19 from the ratchet teeth and the shade will descend. When at the desired position the cord is simply released and the lever falling by gravity will cause the pawl to engage the teeth of the ratchet wheel 14.

It will be noted in Figs. 1 and 2 that the cord. 13 does not bear against the ratchet wheel, hence there is no wear or friction, and also that the collar 15 and circular projection 9 prevent the inner faces of the ratchet wheel and lever from coming in contact.

Having thus described the nature and objects of my invention what I claim as new and desire to secure by Letters Patent, is-

In a device of the character described, the combination of a shade, a roller, supporting brackets therefor, a lever pivoted to one of the supporting brackets at a point between the center of the lever and its lower end, an opening in the lower end of the lever for a cord, a ratchet and drum carried on one end of the roller, one of said brackets diagonally slotted to receive one end of the roller and provided with a circular bearing at the end of the slot for the roller, the upper end of said lever of relatively vbroad curved formation and a pawl thereon to engage or disen- 10 gage the ratchet when the, cord is pulled or released to raise or lower the shade.

In testimony whereof I have signed my name to this specification.
